Enzyme Information

1.12.98.2

5,10-methenyltetrahydromethanopterin hydrogenase.

based on mapping to UniProt Q58194

H(2) + 5,10-methenyltetrahydromethanopterin = H(+) + 5,10- methylenetetrahydromethanopterin.

-!- Does not catalyze the reduction of artificial dyes. -!- Does not by itself catalyze a H(2)/H(+) exchange reaction. -!- Does not contain nickel or iron-sulfur clusters. -!- Formerly EC 1.12.99.4.
